Problems solved by technology

However, the real-time traffic information is not clearly expressed; (3) The coverage of real-time traffic information is limited
The real-time dynamic information system of road traffic flow has not been fully established, and the traffic information provided by relevant departments every 5 minutes can only be static and quasi-real-time
At the same time, since the travel time of the road segment is related to the moment when the vehicle passes through the road segment, but the moment when the vehicle arrives at a certain road segment at the beginning of the search is unknown
The originally clear road segment at the beginning of the search may be blocked before the user arrives

Embodiment 1

[0067] refer to Figure 1 to Figure 10 , a road traffic information cloud computing and cloud service implementation system based on Internet of Things technology, including vehicle-mounted GPS, GPS base station, relay station and information center installed on the mobile vehicle, the information center includes mobile Data storage server for vehicle GPS data, cloud computing server for sensing traffic status, road traffic information platform server and GIS server for providing traffic information cloud services; between vehicle GPS, GPS satellites, GPS base stations, relay stations and information centers communication such as figure 2 shown;

[0068] Described vehicle-mounted GPS comprises three parts of antenna unit, receiving unit, calculation unit and mobile communication unit, as figure 1 As shown; the main function of the antenna unit is: when the GPS satellite rises from the horizon, it can capture and track the satellite, receive and amplify the GPS signal; the m...

Embodiment 2

[0119] A road traffic information cloud computing and cloud service implementation method based on the Internet of Things technology. The process of the road traffic cloud service implementation method is as follows: the user sets the start and end points through the network computing device, and the network computing device can be a PC, a mobile phone, a navigator etc., the cloud computing server end generates a URL according to the starting and ending point positions set by the user, and sends this URL to the road traffic information platform server and the GIS server, and then waits for the road traffic information platform server to and the results sent back from the GIS server. After receiving the URL sent by the user, the road traffic information platform server and the GIS server analyze the URL to obtain traffic cloud service types, such as route calculation, map profile, positioning, information query, CMMB service, etc. The service type can be obtained through the va...

Abstract

The invention relates to an implementation system for cloud calculation and cloud service of road traffic information based on a technology of internet of things. The system comprises a vehicular GPS (global positioning system) arranged on a mobile vehicle, a GPS satellite, a GPS base station, a relay station and an information center, wherein the information center comprises a data storage server used for receiving and storing the data of the GPS on the mobile vehicle, a cloud calculation server used for sensing the traffic state, a road traffic information platform server used for providing the cloud service of the traffic information and a GIS (geographic information system) server; and the invention provides an implementation method for cloud calculation and cloud service of the road traffic information based on the technology of the internet of things. According to the invention, the road information acquisition and the road information service are integrated, the traffic detection for existence of any vehicle is realized, the detection and sense of a road traffic system in large scale are realized, and the traffic state is evaluated, guided and controlled based on the data, thereby providing the real-time road condition information and navigation service to a traveler.

Description

technical field [0001] The invention belongs to the application of GPS positioning and speed measurement technology, GIS technology, cloud computing technology, urban road digital coding technology and network communication technology in road traffic state detection, especially an intelligent road traffic information service based on Internet of Things technology. Background technique [0002] Today's traffic problems have become a global "urban problem", and traffic congestion is the main manifestation of the city's "traffic disease". The "cause" of urban traffic congestion stems from a variety of factors, and traffic congestion directly affects the quality of people's travel, especially those who use vehicles for transportation. Congested road vehicles, frequent traffic accidents, deteriorating traffic environment, energy shortage, and increasing environmental pollution. These increasingly serious traffic problems are related to the basic concepts of modern traffic, namely...
